The Bears thought they replaced Blake Costanzo, who led them with 375 special teams snaps last season, when they signed veteran linebacker Jordan Senn March 13, the opening day of free agency. But he was in the club's first wave of cuts earlier this week, indicating a miss. Wide receiver Eric Weems and safety Craig Steltz, who each logged more than 300 snaps on teams last season, are departed. Weems hooked on with the Falcons quickly. Steltz, coming off groin surgery in the offseason, wasn't moving well enough. Costanzo wasn't moving real well at the end of last season. He's already out of the picture with the 49ers after being released from injured reserve.
